Face (Fig. 2) finely granulose, with sparse fine punctures and yellowish brown setae, near upper margin with a small median tubercle. Inner orbits of compound eyes distinctly emarginate opposite antennal sockets, with regular yellowish brown setae. Posteromedian portion of vertex (behind ocellar triangle) with weak longitudinal groove (Fig. 3). Lower-posterior corner of mesopleuron with strong swelling (Fig. 5). Wings (Fig. 7) yellowish brown, semi-hyaline. Longer spur of mid tibia approximately 0.8 times as long as first tarsomere. Tergite 1 about 2.3 times as long as apical width, distinctly convex basal of spiracle.

Clypeus approximately 2.5 times as wide as long, finely granulose, with indistinct, sparse brown setae; apical margin with distinct median emarginate. Mandible particularly strong, basal portion with sparse brown setae. Malar area finely granulose, approximately 0.5 times as long as basal width of mandible. Inner orbits of compound eyes distinctly emarginate opposite antennal sockets. Gena broad, evenly convergent backwardly, with dense, fine punctures and yellowish brown setae. Vertex (Fig. 3) with yellowish brown setae and weak median longitudinal groove. Ocellar triangle with distinct punctures. Postocellar line approximately 1.3 times as long as oculo-ocellar line. Lower median portion of frons slightly concave, with fine arched wrinkles; lateral portion with dense yellowish brown setae. Lateral margin of antennal socket with small tubercle.

Mesosoma. Pronotum (Fig. 5) with granulose texture and dense yellowish brown setae; Epomia absent. Mesoscutum (Fig. 4) evenly convex, anterior and lateral portions with distinct dense punctures and brown setae, posteromedian portion with fine, indistinct punctures. Notaulus weak. Scutoscutellar groove smooth, shiny. Scutellum almost rounded convex, with fine dense punctures and long brown setae. Postscutellum evenly convex, with fine punctures. Mesopleuron (Fig. 5) granulose with even fine punctures and brown setae; speculum very small, with fine punctures; mesopleural fovea small, shallow, smooth. Lower-posterior corner of mesopleuron strongly convex. Metapleuron evenly convex, with texture as that of mesopleuron; lower posterior portion with indistinct oblique wrinkles. Submetalpeural carina complete, strong, anterior portion strongly raised. Sulcus between postscutellum and propodeum deep, shiny, with short longitudinal wrinkles. Propodeum (Fig. 6) short, slightly oblique; weakly, finely reticulate, with dense yellowish brown setae; spiracle convex, oblique elongate, 3.0 times as long as width, located at basal 0.3.

Distribution

CHINA: Hunan, Zhejiang.

Remarks

This new species is similar to Rh. maculicornis Sheng et al., 1995, but can be distinguished from the latter by the following combination of characters: lower-posterior corner of mesopleuron with strong convexity; gena, vertex, mesopleuron and mesosternum yellow; and propodeum yellowish white. Rhynchobanchus maculicornis has lower-posterior corner of mesopleuron slightly convex; gena, vertex, mesopleuron and mesosternum black; basal portion of propodeum black, median reddish brown and apical yellow.

Etymology

The name of the new species is derived from Latin words “flavi” (yellow) and “maculatus” (macula) after its body with large irregular yellowish spots.
